Circuit 2
Output disable (active high); there are internal pull-down resistors, so the device will be active with
no connection; “HI” puts the output in high impedance state

ENABLE
Circuit 2
Device enable (active low); there are internal pull-down resistors, so the device will be active with
no connection; "HI" puts device into power-down mode
